There are many carbon calculators around but here are three of our favorites


1. The Environmental Protection Agency’s Household Emissions Calculator

  • The EPA’s online calculator allows you to determine your household’s greenhouse gas emissions.
  • Their website also provides suggestions on actions you can take to reduce your emissions.

2. The Nature Conservancy Carbon Footprint Calculator

  • The Nature Conservancy, a conservation organization and 3Degrees partner, hosts a calculator on its website that allows you to calculate both your personal greenhouse gas emissions, as well as those of your entire household.

3. Safe Climate Carbon Footprint Calculator

  • A project of the World Resources Institute, a global environmental think tank, this calculator can be used by individuals outside of the U.S. and Canada.

This is just a partial list of carbon calculators available. Of course we can’t list them all but if you have a suggestion please let us know. And if you are a business, non-profit or government agency ready to supporting renewable energy and mitigate the impact of your unavoidable carbon emissions we want to hear from you. We have options ranging from Renewable Energy Certificates (RECs) to carbon offsets to direct procurement.
